Poor Service delivery from games (Gateway Branch )

i have made a purchase for a new gas electric stove on Friday 26-06-2020, i have paid the full amount the sales men confirmed that the unit will be deliverd over the weekend between 8-4pm, and he would contact me if there was any problems. i have not recieved my stove and no one has contacted me. This is not ethical practices why lie to customers , i have since tried to contact the gate -way branch but they do not pick up the phone, why take the consumers money and make us chase up for our goods , the call are shared calls which i now have to pay for because of there lack of service delivery. the saleman ensured me that my unit will be delivered over the weekend. The games stores should operate ethically and try to obeserve good businees practices,
